If you know a good carpenter or mechanic they have a tool to remove the screw driver. My husband has done this many times. If you open anything first take photos along the way for reference to put everything back. Use one of those magnetic tins for pins and keep near for the screws and any little pins. If you don't have a manual for the machine see if you can find it on the internet. If you know where the smoke was coming from look into that area and see if there are any hot marks. Take a photo of it. Some one on line may be able to tell you the problem. it will be worth the money. Can you take a photo and text it to a friends email then have them post for you? My sons do that often.
